Centenex BAMAGELLANPromark3 Survey GPS Battery

This Centenex Electronics battery replaces the original power pack for Magellan Promark 3 survey GPS receivers and compatible Thales MobileMapper CX and CE units. It delivers 3.6 Ah at 3.7 V for 13.32 Wh of capacity in a lithium-ion cell. The black housing measures 72.33 x 53.26 x 15.25 mm and weighs approximately 100 grams. One battery is supplied per pack.

Thermals Noise and Power Draw in Normal Use

Lithium-ion chemistry keeps self-discharge low so the pack holds charge between field sessions. No fan or active cooling is present; the cell runs at ambient temperature during typical survey workloads. Current draw follows the GPS receiver’s own power management, so runtime scales with satellite acquisition rate and screen brightness. The 3600 mAh rating supports extended logging without mid-day swaps.

Upgrade Path and When the Jump Is Worth It

This unit replaces OEM part numbers 111141, 37-LF033-001 and FS207 when the original pack no longer holds a full day’s charge. It is not for users who need hot-swap dual-battery bays or higher-voltage packs for non-Magellan hardware. The capacity increase over aged cells restores full-day operation for Promark 3 and MobileMapper CX field crews.

Questions about this item

How do I install the battery in my Magellan Promark 3 and which step is often missed?

Slide the battery into the compartment until the latch clicks; the step users miss is confirming the 72.33 x 53.26 x 15.25 mm pack sits flush so the contacts align with the 3.7 V rail.

What maintenance or replacement will this Li-ion 3600mAh pack need over time?

Expect capacity to fade after several hundred charge cycles; plan to replace the 3.6 Ah unit when runtime drops below your survey day requirements.

What limit appears first during continuous GPS logging with this 13.32 Wh battery?

The 3600 mAh capacity is the limiting factor; sustained logging will drain the pack in a single field session before thermal or voltage limits are reached.
